5. A/C or DEF Switch:
INSPECT INDICATOR LIGHT OPERATION
(a) Connect the positive (+) lead from the battery to terminal
A−9 and the negative ( −) lead to terminal B−18.
(b) Push the A/C or DEF switch button in and check that the indicator light lights up.
(c) Then, connect the positive (+) lead from the battery to ter-
minal A−13 and check that the indicator dims.
If operation is not as specified, replace the A/C control assem-
bly.

If continuity is not as specified, replace the A/C control assem-
bly.
9. INSPECT A/C OR DEF SWITCH CONTINUITY
Check that there is continuity between terminals B− 6 and B−17
intermittently each time the A/C or DEF switch button pressed.
If continuity is not as specified, replace the A/C control assem-
bly.
10. INSPECT TEMPERATURE CONTROL SWITCH RESIS-
TANCE
(a) Measure resistance between terminals B −1 and B−2.
Standard resistance:
Approx. 3.0 kΩ
(b) Check that the resistance between terminals B −1 and
B−3 increases from 0 to approx. 3.0 k Ω when the switch
knob is turned from COOL to HOT.
If operation is not as specified, replace the A/C control assem-
bly.

INSPECTION
1. INSPECT SHIFT LOCK CONTROL ECU
Using a voltmeter, measure the voltage at each terminal.
HINT:
Do not disconnect the ECU connector.
2. INSPECT SHIFT LOCK SOLENOID
(a) Disconnect the solenoid connector.
(b) Using an ohmmeter, measure the resistance between ter-
minals.
Standard resistance: 20 − 28 Ω
If the resistance is not as specified, replace the solenoid.
(c) Apply the battery positive voltage between terminals. At this time, confirm that solenoid operate.
If the operation is not as specified, replace the solenoid.
